Scientists Finally Explain Crab Pulsar's Mysterious 'Zebra Stripe' Radio Patterns
For decades, astronomers were baffled by distinctive "zebra stripe" patterns of bright bands and complete darkness in radio waves from the Crab Pulsar. New research concludes the phenomenon results from a cosmic tug-of-war between the pulsar's plasma and gravity. The plasma spreads light apart while gravity bends it back, generating interference patterns that produce the striking striped appearance.
